If you don't look at the absolute values, but at the improvement, the difference of +20% is not that small. For many, it could make the difference between "too dry mucous membranes" and "rather unproblematic." Of course, everyone is different.

So please, have wooden windows painted black on the inside and clad with aluminum on the outside. In front, luxury blinds with "Smart" Home control. But want to save on the enthalpy exchanger... tss, youth these days :oops:

Stop stop, this has nothing at all to do with saving money (after all, this is about the indoor climate, I would gladly give up a few Hue lamps for that). Not nice!

If you google the thing, one of the first things you find is a post in a forum about Zehnder exchangers and related problems concerning odor nuisance and distribution in all rooms.
At first, I thought, okay, then I’ll just turn off the humidity function, which was quickly done after I understood that the entire filter system is different and not just a (cost-effective replaceable filter).

That’s why I have concerns and further questions on the topic. I definitely don’t want to buy the wrong thing only to regret it later, and if strange odors ruin the house for me, it will be skipped and instead operated with humidifiers as needed… Quite simple…

The only positive thing in your last post was about youth, which almost makes an old geezer happy who likes to indulge in luxury for his hard-earned money, of course always ;).

Hey, that was meant ironically. I would never seriously accuse you of being frugal :p

We have an activated carbon filter in front of the supply air distributor (which is very easy with Zehnder using these Comfowell boxes). Not because of internal odor transfer, but because of the good country air (which is currently replaced by the stove and fireplace season). It works great and should also possibly filter out internal odors (which I don't believe in anyway). So no panic.

That's how it looks, with the flood of fireplace owners in our neighborhood it was stupid without activated carbon, with it it's perfect! Mounted in the same position as Enthalpy and pure heat exchanger didn't make any difference

Internal odor distribution at Zehnder also had no problems with either enthalpy or pure heat exchanger.

We had both variants, since initially the pure heat exchanger was mistakenly installed and we left it running until the first heating season. Then the humidity levels plummeted with the drop in outside temperatures, since then the system has been running with the enthalpy exchanger to our utmost satisfaction in its second year.

All good, glad we cleared that up ;). Your points for this additional activated carbon filter sound super interesting (all the things you have to think about, man man man)! Is this a special Zehnder solution or is there a general solution that can also be installed in a new build, for example with Viessmann? Both country air and chimney could definitely be an issue for us...
